As I’ve written in other posts, I’ve been relying heavily on ranged attacks from bands of Elves.
Recently, while closing out Black Water Bog, I had a huge army of Elvin Archers aggressively cleaning up the zDwarf towns in the north by charging the towns, which by this point are severely diminished. So with 30 minutes until battle at Rams Crag, a group of 25 Archers knocked off the last few defenders before the battle had even commenced. Hooray, but when I immediately tried to move them to the next town and was unable because it still showed combat occurring in 30 minutes. I rationalized it by thinking it would take an army preparing for battle some time to prepare to move again.
So Jay feature or oversight?
